2.2 AP300X with MSD50 Stern Drive unit
Note ! The information on this page applies if your autopilot is driving a Robertson
MSD50 Stern Drive.
The MSD50 Stern Drive unit has a relative feedback signal which
needs a zero point setting after the autopilot has been turned on.
Refer to page 1-1 of the MSD50 manual for further information.
Zero point setting
Note ! If you do not need a rudder angle display when leaving the dock, just
steering the boat manually on a straight course and press the AUTO button.
The zero point is then set automatically.
If you prefer to use the rudder angle display when leaving the dock,
proceed as follows:
After turn on press the STBY button once more to display the rudder
angle.
10
STBY
Display is alternating between port and starboard rudder to indicate
that the “rudder” zero point need be set.
Use the wheel to bring the “rudder” to midship position: Turn the
wheel from lock to lock (H.O. to H.O.) and count the exact number of
turns. Then start from one lock position and turn the half number of
turns.
Press AUTO and then STBY two times with an interval of approx. 2
seconds between the two. The zero point is now set and the display
will read:
00
STBY
Operation
Use the operation instructions on the following pages. There is no
need for further zero point setting until next time you turn the
autopilot on.
